    Default Thermaltake Toughpower 750 owners: Please Be Informed

    That your Toughpower 750 series is known to have the *buzzing* issues that I and others have been complaining about.

    At this point it's not known whether it's a complete lot/batch or just a partial. IT INDEED IS FACT THIS ISSUE IS KNOWN BY THERMALTAKE, AND YOU KNOW DAMN WELL THEY DO NOT WANT US TO HAVE THIS INFORMATION.

    Please be sure to use this information when it's time to pick your next psu.

    I'm on my third 750 now, and this one still *buzzs* to beat hell when under load.

    Guess the secrets out Taiwan

    Could we make this a sticky until TT resolves this issue? thanks

    Did you ever try isolating the PSU from the motherboard outside of a case like JonnyGURU suggested in your other thread to see if it's a component on your board buzzing or if it actually eminates from the PSU?

    Yes I did, and I tried it in another case, along with my MSI K8N Neo 4 F, as well as outside of the case.

    As stated in the topic of this thread...TT has full knowledge of this issue, you going to have to trust me on this, it IS fact. It's also fact, that I'm just one of many 750 users who are experiencing this issue.

    Eeep... It's a good thing that PSU is out of my budget... Cuz I was kinda considering it for a while.

    Anyway... If it's buzzing... A buzz is a mechanical vibration... I wonder what component is causing it. You could always do what I do with all-tube guitar amps: Open the thing up, power it up, and poke around with a wooden chopstick. That's how amp techs fix parasitic oscillations in tube amps and it might help you isolate which part is vibrating.

    If I take off the housing, then my warranty is void. It's fine on the desktop, but once you put it under load, it sounds like a colony of bees is nesting next to me.

    The idea of using chopsticks is intriguing though!

    You're getting bees? Mine sounds like crickets.
    I wonder which is more irritating.

    Ah, that is true... I always forget about warranties. LOL Sounds to me like a spot of hot glue or some wax potting could fix the problem. Maybe it's a transformer that wasn't potted correctly. Hmmm...

    Yeah, the chopstick idea is great. A piece of wood you can poke with and won't get you zapped. At least a computer PSU drops the voltages, but the Amperage is still high. Inside a guitar amp, you're working with anywhere from 200VDC (in a small, single-ended Fender combo) to 600VDC (on the power tubes of some Marshalls and MusicMan amps). I saw a video of a guy get tossed against a wall by a guitar amp after getting zapped by it.

    OK Sphere, I'll trust you that it's a known issue with Thermaltake.

    Can you guys post MP3 files of this noise? That'd be nice.

    Sure, in your opinion, what would be the easiest way to record it?

    GilmourD...I'll remember that , I've got an Ampeg VH 140C that's gonna' need to hit the shop, every now and then it fades in and out and I can't figure out why, but I do know I won't be working on it....but, it's not a tube.

    EDIT: Actually I can plug a mic in the lappy, and record it from there.....I'll give it a go.

    That mic should do a good job. Doesn't need to be studio quality audio.

    That's solid-state, eh? Hmmm... Fading in an out on a tube amp would usually be a tube... Does it do it when it's warmed up, or right as you power it up? And is it more of a cut-out, or does it fade out gradually? If the amp has reverb, try turning the reverb off and see what happens.
